Salesforce Software Engineer interview questions

I was first contacted by email that I would have a phone interview. In the phone interview they asked me simple questions about my computing background as well as what I have done at Purdue University. They then thanked me and told me I would receive another phone interview shortly. I got another email, another similar phone interview, and then they told me about a third phone interview, this time in a group setting. After this I received an offer a few weeks later.

One phone call interview : general discussion about the position, the team and projects. One coding challenge : build an application with some specific requirements. Several interviews in a row with directors and technical team: discussion about personal background, motivation, previous projects. Some logic coding challenges and front end challenges.
